, FOLDING CAN OPENER.

Application filed August 81, 1923. Serial No. 800,419.

To all whom-it may concern:

Be it known that I, KNUD F. Scmomenu, a citizen of the United States,and a resident of Chicago, in the county of Cook and State of Illinois,have invented a new and useful Improvement in Folding Can Opener, ofwhich, the following is a full,

clear, and exact description.

My invention relates to improvements in can openers, especially thosewhich are designed to be carried in the pocket, and it consists in thecombinations, constructions, and arrangements herein described andclaimed. 1

An object of m invention is to provide a can opener in w oh the cuttingblade is' foldable with a guard for holding the blade in its foldedposition so that it may be carried in the pocket without any danger ofcutting the latter, or of injuring the owner.

A further object of my invention is to provide a simple folding canopener which may be folded into small compass so as to take up verylittle room, and which may be used by. campers, tourists, or the like.

A further object of my invention is to v provide a device which can bemade up at small cost since it is entirely stamped out.-

Other 0 jects and advantages will appear in the following specification,and the novel features of the invention will be particularl pointed outin the appended claim.

y invention is illustrated in the accompanying drawings forming part ofthis application, in which Figure 1 is a perspective view of the deviceshowing the guard thrown back.

Figure 2 1s a view of one face of the device showing the guard in itsclosed position,

Figure 3 is a view of thevopposite face,

Fi 4 is a side elevation of the can, showing the manner in which thedevice is manipulated, and

Figure 5 is a section through the can with the cutter in position atright angles to the position shown in Figure 4.

In carrying out my invention I provide a body portion 1 which consistsof merely a flat metal plate. It is provided on one edge with a hook 2which may be used to open caps of bottles. One end of the. body portionis rounded as shown at 3.

On one side, there is astraight edge 4 against which a hinged cutterblade 5 bears portion 7 arranged to receive the loop, and is when thedevice is in operating position. The body portion has an extension 6which is bent into the form of a loop or hinge portion. The cutter blade5 has a cut away provided with inwardly extending inte ral pintleportions 9. around which the hinge portion 6 is bent. The cutter blade 5has a sharp point 10 and a curved cutting edge 11. The body portion 1has a recess 12 of the shape shown in the drawings. This provides asharp fulcrum point 16.

A guard 13 consisting of a single piece of metal bent back upon itselfas shown at 14 is pivotally hinged to the end of the body portion bymeans of an eyelet 15.

From the foregoing description of the various parts ofv the device theoperation thereof ma y be readily un erstood. Normally the device isclosed as shown in Figures 2 and 3. In these figures, it will. be seenthat the portion 14 overlies the end of the blade 5 when the latter isswung in a position adjacent to the body portion, so as to cover thepoint 10. The device cariybe carried 1n the pocket without any danger ofcutting the clothing or person of the owner. When it is desired to usethe-knife for opening cans, the guard 13 is thrown back and the blade 5is opened until it is at right angles to the body portion 1, when theedges 5 will engage the edge of the body portion so as to prevent themovement of the blade past a position perpendicular to the plane of thebody portion.

The point 10 is applied to the top of the can inside of the bead, andthe fulcrum point 16 is brought underneath the bead on the outsidethereof, the guard first being swung into closed position. Now, by ress-I ing downwardly with the thumb, as s own in Figure 4, the cutter willbe forced downwardly to out the can, the device swinging about thepoints 16 as a fulcrum. By raising the cutter and shifting the .fulcrum100 I point toward the body, i. e. toward'the right in Figure 4, the outcan be continued all around the can. The device is simple inconstruction, and

therefore is not liable to easily get out of- 105 order. It is compactand when not in use can be carried in the'pocket without anyinconvenience.

After use the blade is folded and the guard is swung into position overit. The can 110 Q memes opener may be carried in the pocket or it arecess to permit the entrance of a portion may be suspended from a keychain, and of the can, and bein provided with a fulthe e elet forms ameans for suspension. erum point on the e to which the blade 15 I c aim:is hinged, and a guard hinged to said body 5 A can opener com nsmg aflat body porportion and-havin a part bent back upon tion, a bladehinges at one edge of said itself, said bent bae portion bein arrangedbod portion and arranged to swing at ri ht to envelo a portion of thebod? and the ang es thereto, aportion of said blade bemg pointed e ofthe blade adjacent thereto, II arranged to enga the edge of the bodythereby be ding the blade in its folded posi- 10 rtion so as to imit itsmovement, said tion.
